FIREARM.

Application filed August 6, 1919.

T 0 (LU whom it may concern.

Be it known that I. THOMAS A. RYAN, a citizen of the United States, residing in the city of Yonkers, county of Vestchester, in the State of New York, have invented new and useful Improvements in Firearms, of which the following, with the drawings, is a description.

My invention relates to improvements in firearms of the magazine type, whereby, with each operation of the arm, simultaneously, the discharged shell from the barrel, and a loaded shell from a tubular magazine set under and parallel with the barrel, are driven into the chambers aligned with the barrel and the magazine of a two chambered carrier, and the discharged shell of the previous shot is driven from the carrier chamber and the arm through the ejecting chamber, the port of which is opened and closed by a shutter connected to the breech-bolt, the shutter carrying and connecting the mechanism to rotate the carrier until the positions of the chambers are reversed, carrying a 1 loaded shell from the magazine which is driven from the carrier chamber into the barrel by the breech-bolt, and carrying the discharged shell from the barrel, which is driven from the carrier chamber and the arm, by the loaded shell as it enters the carrier chamber from the magazine, the carrier rotating between the backward and forward stroke of the breech-bolt on a cocking rod connecting the magazine and the breech bolt, the rod cocking the arm, the arm operated by the discharge, or by a handgrip on the magazine.

The invention should be readily under stood from this description and specifications and the accompanying drawings in which each part is shown separately and the parts assembled showing the operation of the arm.

Fig. 1 is a longitudinal view partly in cross section showing the several operating mechanisms in the postion they occupy immediately after firing and the instant the carrier makes its half turn. Fig. 2 is a similar view showing in cross section the parts not shown in Figure 1. In this view the arm is shown cocked ready to fire. Fig. 3 is a similarview to Figure 1 showing the tumbler replaced by a hammer, the firing pin carried in the breech-bolt and the shell grip in the breech-bolt head.

The arm is assembled and operates as follows: The breech-end of the barrel 3 and the lug 3 fit the frame hole 2 and the recess 2 and are held locked, by the rod 12 in the barrel lug hole 3 An L shape breech-bolt 10 has a center hole, in which slides the reduced portion of a firing pin 11, the diameter of the large portion of the firing pin 11 and the bolt 10 being equal, and a sliding fit for the frame hole 34, compressing the spring 32 as it moves back the fiat portion 10 sliding in a channel connecting the hole 84 with the hole 35 in which slides the round part 10 compressing the bolt spring 33. Projecting outward at right angles from opposite sides of part 10 are arms 10 the ends of which are adapted to slidingly engage the upper slots 18 of the levers 18. The cocking rOd 12, connects with the center of 10 and projects backwardas shown at 10. From the under side of 10 a lug proj ects downward holding the shells in the carrier and the magazine when'the position of the arm is not level. The levers 18 are movably inned through the center hole 18 to the side walls of the ejecting chamber 36 and the lower slots 18 movably pinned to the lugs 21 of the shutter 21. The lever 20 is movably pinned near its pointed end to the inner face of the shutter 21, and carries slidably in the hole 19 and the keyway 19 an angle member 19, the upright leg of which is encased in a spiral spring 19 and having along its side a longitudinal key 19 The shutter 21 slides in channels cut in each side of the port of the ejecting chamber 36 opening and closing the port of the ejecting chamber. A flat spring 22 one end of which is secured to the frame, projects backward diagonally, having a lateral alignment with the lever 20, and is engaged by the lever 24) as the shutter 21 moves back. It will be noted, that as the shutter 21 moves forward, the end of the spring slides along the lever 20, but before the end of the spring 22 has passed the pivot point where the lever 20 is pinned to the shutter 21., the end of the angle member 19 has entered the hole 9 or 9 of the carrier 9, this holds the lever 20 against movement, thus the lever 20 forces back the spring 22 asthe shutter completes its forward stroke. hen the shutter 21 has completed its forward stroke the projecting end of the angle member 19, is length deep in the hole 9 or 9 of the car- 'rier 9, and the flat spring 22 is forced back until it is straight. It will be further noted, that at this point the rotating mechanism holds the carrier 9 in a. cocked position, ready to be sprung, the instant the breechbolt 10 moving backward out of the upper carrier chamber clears the carrier, the stored energy in the spring 22 forcing the lever 20 connected to the carrier 9 by the angle member 19 across the fa e of the shutter 21, the shutter 21 being, slightly concaved in the path of the lever 20 to facilitate the turning of the carrier 9, thus overcoming the tendency of the carrier to hold on a dead center, as the lever 20 carrying the angle member 19 turns the carrier 9 until the position of the carrier chambers have been reversed, the loaded shell being now in the upper and the discharged shell in the lower chamber of the carrier 9. As the carrier 9 completes its half turn the breech-bolt 10 moves forward through the upper carrier chamber forces the loaded shell from the carricrchamber into the barrel, and the discharged shell in the lower carrier chamber is forced, from the carrier and the arm throughthe ejecting chamber 36, by a loaded shell fed from the magazine into the carrier chamber as the breech-bolt makes its backward stroke.

The levers impart a movement to the shutter 21 in adirection reverse to and simultaneous with the mo ement of the breech-bolt 10, the shutter closing the ejecting chamber port, as it moves back, the projecting end of the angle member 19, withdrawing said member from the'carrije'r hole 9 or 9*. The lever 20 is' engaged by the end of the spring 22, forcing the lever 20 back after it passes the pivot and setting the projecting end of the angle member 19 in align ment with the hole 9 or 9* in the carrier 9 for the next shot. 4 The shell magazine, set un'der and parallel to the barrel, is compo'sed of two tubes Q6 and 7 and a plunger 23, also a hand-grip 8,

the plunger 23 sliding endwise in the inner tube 6, and has set longitudinally, movingly pivoted at one end in a slot a lever 23 having a pointed end held outward by a spring set under the lever, a bridge in the upper part of the slot engaging the end of the lever holding same in the slot, the lever having pinned at each side fiat springs, the projecting ends of the springs having lat eral alignment with the V shape slots 6 cut in the edge of the longitudinal slot 6 of the tube 6, in which the lever slides, the pointed end of the lever engaging the longitudinal spaced teeth out in the inner face of the outer tube 7, aligned with the slot B of the inner tube 6, the spacing of the teeth corresponding to the length of the shell or cartrid e to be used in the arm. lVhen the outer tube 7 is moved backward the plunger 23 moves with it, and is held in its advanced position by the projecting flat springs on either side of the plunger lever 23 engaging the V shape slots cut in the edges of the slot 6 of the inner tube 6, as the outer tube 7 moves forward, the plunger lever engaging an advanced tooth in the outer tube 7. setting the'magazine to eject the next shell. cured to the frame by setting the cross slot 6 of the inner tube 6 in engagement with the projecting pin 2 in the frame hole 2 and connecting the nipple 13 turning in hole 7 of the lug 7 of the tube 7 with the cocking rod This connects he magazine with the breech-bolt 10 and the shutter 21 carr ing the rotating mechanism, also with the firing mechanism. The arm is operated automatically by the force of a discharged shell, recoiling carrying the breech-bolt back compressing a spring in the path of the breech-bolt and a spring compressed by a firing-pin carried in the breech-bolt, a cocking rod setting the firing mechanism, and cocking the gun, the stored energv in the springs 32 and 33 set in the holes 3e and 35 the breech-bolt spring 33 setting the breech-bolt loading a shell from the. magazi'rie, by the rotating inecl'ianism, and closing the port of the (16(il11f9j chamber, or the bolt is operated by a to and fro movement of the handle 8. The changes in the construction of the gunwith a hammer is shown in Figure 3. The firing-pin spring 32, the tumbler 15 and the locking lever are not used, a trigger and hammer 28, having a spring, hole is cut through the rear of frame the enlarged end of the firing pin is made longer and has no notch, the smaller end having a pointed cap screwed on its end holding the firingpin in the breech-bolt. In Figure & the. arm is shown Without the breech-bolt spring 33, having hammer 42, 'w1th a tumbler All movingly pivoted in the recess 4:2 the ed s of whi'chlare cutout as 42 The hammer is held cocked and locked The magazine is se by a sear 16, the head of the sear 16 set by the sear spring in engagement with the cutouts 42 when the hammer flies down firing the arm, locking the hammer and the breech block against the discharged shell in the barrel. As the hand-grip is moved back the cocking-rod engages the tumbler 41 the L shape end forcing the sear 16 from the cutouts 42 cocking the hammer, the sear 16 moving back under the point 42 When the trigger 39 is pulled it forces the sear 16 into the hole 43 firing the gun. The shell extractor in the head of the breechbolt is formed by the two diametral L shape ends 29 and 29 engaging the rims or grooves of a shell, the lateral projections sliding in the longitudinal keyways 9, 9 9 and 9 cut in the carrier chambers the end projections standing in the circular keyways 9 and 9 as the carrier turns, and fitted recesses cut in the breech end of the barrel.

It will be noted that the arm can be operated -automatically, semi-automatic, or by the hand-grip on the magazine, and is adapted for a hammerless or hammer fire.

In Fig. 1 and Fig. 2 the automatic is shown, the explosive force of the discharged shell recoils the breech-bolt back compressing the breech-bolt spring 33, and cocking the arm, the stored energy in the spring completing the operation. When a breechbolt spring 83 is not used, the explosive force of the discharged shell forces the breechbolt back and cocks the arm and the operation of the arm is completed by moving forward the hand-grip, or the entire operation of the arm, performed by a to and fro movement of the hand-grip. When the arm is automatic in operation by using the breech-bolt spring, it does not prevent the use of the handgrip, the arm being locked or the hammer held While the mechanism is operated by the hand-grip to load the magazine or adjust the shells.

The magazine is loaded, by turning the inner tube 6, which throws the lever 23 of the plunger 23 out of engagement with teeth cut in the tube 7, and the flat springs on the sides of the lever clear of the V shaped slots 6 cut in the edges of the slot 6 of the tube 6, which permits the plunger 23 to slide back as the shells are placed in the tube 6 through the ejecting chamber 36, or the nipple 13 can be unscrewed from the rod 12 and the magazine removed from the frame while the shells are placed in the tube 6.
